LUBRICATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 688,434, dated December 10, 1901.

Application filed April 18, 1901- Serial No. 55,763. (No model.)

T6 at whom it may concern: v

Be it known that I, FREDERICK \V. PAR- sONs,a citizen of the United States of America, and a resident of Elmira, in the county of Ohemung and State of New York, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in lubricating devices, and such improvements are particularly adapted for use in connection with lubricating devices for engines.

My invention consists in the provision of an oil-well and a rotary disk partially immersed in the oil contained therein, together with a scraper having one end in contact with the periphery of the disk, the said scraper inclined toward the said disk in a direction opposite to the direction of rotation of the saiddisk, and an oil-conduit in communication with the opposite end of said scraper, from which the oil may be distributed through distributing-channels to various points, as may be desired.

When this invention is applied to an engine, the oil-well may conveniently be the crank-pit, and the rotary disk the crank-disk, of the engine.

My invention further consists in providing a connecting-rod in connection with the said disk, which has an open-top oil receiver or receivers therein, and having a channel or channels leading from thence to a point or points desired to be lubricated, the said receiver or receivers adapted in their movement to receive oil from the said oil-conduit.

The objects of my invention are to improve generally such type of lubricating devices to provide a lubricating device that will oper-' ate effectively at all speeds, that in operation will not unduly agitate the lubricant, and that will be simple of construction, economical in operation, and composed of but few parts.

My invention further consists in certain details of construction and combination of parts,

as will be hereinafter more fully set forth,

and other advantages therefrom will appear hereinafter.

I will now proceed to describe a lubricating device embodying my invention and will then point out the novelv features in claims.

In the drawings which form a part'o'f this specification, Figure l is a view, partially in side elevation and partially in longitudinal section, of an engineprovided with a lubrieating device embodying myinvention. Fig. 2 is a top view of certain parts thereof. Fig. 3 is a detail sectional view of one end of an improved connecting-rod employed.

The engine herein comprises a combined bed-plate and engine-frame a, a steam-cylinder 1), a piston and piston-rod c, a cross-head d, a crank-shaft e, mounted in bearings in the said engine-frame, a crank-disk f, carried by said shaft 6, a crank-pin g upon said disk, and a connecting-rod h, connecting the crankpin g with a wrist-pin carried by the said cross-head. The crank-pit formed in the combined bed-plate andengine-frame serves as a well or reservoir for lubricating-eil, and the diskf is arranged to be partially immersed in the oil contained therein, as clearly shown in Fig. l of the drawings. A scraper t' is secured to a fixed point in the apparatus, and the said scraper has one end thereof in contact with the periphery of the crank-disk fand is inclined thereto in a direction opposite to the direction of rotation of the said disk. The direction of rotation of the said disk is indicated in Fig. l of the drawings by the arrow, which is shown in proximity thereto. In rotating the disk picks up a certain quantity of oil from the well and delivers such oil to the scraper i. The oil then passes over the scraper and is delivered to a conduit j, from whence it may be distributed through distributing channels to various points, as desired. In the present apparatus the connectingrod h is provided with oil-receivers it, each having an open top and each having a channel leading therefrom to one of the bearings of said connecting-rod. The oil-receivers 7c of the said connecting-rod h are arranged, in their path of movement,to pass beneath points of discharge from the said oil-conduit j. A pipe Z discharges oil from the said conduit to the desired point in the path of movement of that receiver 7c which is at the forward end of the connecting-rod It. (See particularly Fig. 2.) A pipe m leads from the conduit j to an auxiliary conduit 02, and a pipe 0 leads from the said auxiliary conduit 01 to the desired point in the path of movement of that receiver 70 which is at the rear end of the said connecting-rod h. In its reciprocation the connecting-rod will receive a certain proportion of the oil discharged through the pipes on and 0 and will transmit same to lubricate the crank and wrist-pin bearings therein. The surplus oil from the pipe 0 will fall over the cross-head and lubricate the cross-head slide and guide, while the surplus oil from the pipe on will fall back into the oil-well. Distributing-channels may lead from the conduit jto various other points to be lubricated, such as the shaft-bearing, the.

Myimproved lubricating device, while providing for continuous lubrication, effects a considerable saving in the amount of lubricant used, for but a very small percentage thereof is wasted, the said lubricant being used over and over again. Further, the lubricant is not beaten into a foaming condition, such as occurs with the splash system of lubrication commonly employed to eifect this same purpose.

Again, my improved lubricating device is efiective at any speed at which the device may be operated, while the same is not true of centrifugal lubricating devices which have also been employed under similar conditions and for similar reasons.

It is obvious that various modifications of the construction and arrangement of parts herein set forth may be resorted to within the scope of my invention.

What I claim is- 1. In a lubricating device the combination with a well adapted to contain lubricatingoil, and a rotatable disk arranged to be partially immersed in the oil in said well, of a scraper, located at a point above the level of the center of the disk, and having one end in contact with the periphery of said disk, the said scraper inclined toward the said disk in a direction opposite to the direction of rotation of said disk, and an oil-conduit in communication with the other end of said scraper.

2. In an engine, the combination with a cross-head, a crank-shaft, a disk thereon, a

crank-pin carried by said disk, and a connecting-rod connected to the said cross-head and the said crank-pin, of a crank-pit adapted to contain lubricating-oil in which the said disk is arranged to be partiallyimmersed,a scraper, located at a point above the level of the center of the disk, and having one end in contact with the periphery of said disk, the said scraper inclined toward the said disk in a direction opposite to the direction of rotation of said disk, and an oil-conduit in communication with the other end of said scraper, said conduit arranged to supply oil, through distributing channels, to required places throughout the engine.
